arm: mark save_boot_params_ret as a function
As no '.type' was set for save_boot_params_ret in start.S, binutils
did not track whether it was emitted as A32 or T32. By properly
marking save_boot_params_ret as a potential function entry, we can
make sure that the compiler will insert the appropriate instructions
for branching to save_boot_params_ret both for call-sites emitted as
A32 and T32.
